What is an RPZ Backflow Preventer?

First thing’s first: the definition. An RPZ device, or backflow preventer, is used to reduce or eliminate backflow of water in a plumbing system’s water supply. Utilizing a series of valves and releases, an RPZ device removes any instance of contaminated water from the drinking line or any public line from which water is used. According to Illinois law, it is a requirement that all swimming pools, lawn sprinkler systems, and commercial buildings be fitted with an RPZ system to ensure safety of such water supplies. You can read more about the law at the state’s site,

With years of experience working with RPZ devices and other backflow preventers, we here at Vander Vennet will put our expertise and professionalism to work on your property.
